Abstract
Abstract A floating headrest is formed of a unitary member of expanded plastic such as polyethylene. The headrest includes two raised end sections, between which, the rider's head lays. The headrest includes a cylindrical hole bored from the forward surface to the rear surface to allow the insertion of other tubular flotation devices. The headrest is designed such that the center of buoyancy of the combined headrest, said tubular flotation device, and rider is significantly below the surface of the water, leaving the rider's head out of the water.
